The yield gap is real, but it isn't a free lunch

Australia's national gross rental yield on housing reached 3.79 per cent in August 2026, its highest level since 2019, as rents climbed roughly 5.7 per cent over the year while dwelling values eased back from their March 2026 peak. Commercial property, by contrast, is trading on much higher cap rates: valuation firm Opteon's benchmarking put average Australian cap rates in early 2026 at around 6.2 per cent for office, 5.7 per cent for retail and 5.4 per cent for industrial, with all-property averaging about 5.5 per cent, figures echoed closely by KPMG's own commercial property update. That looks like a straightforward premium of two percentage points or more. It isn't quite apples to apples, though: a residential yield is almost always quoted gross, before the landlord's rates, insurance, repairs and management fees come out, while a commercial cap rate is usually calculated on net income, after most of those costs have already been passed through to the tenant. Adjust for that and the true gap narrows, but a real premium still remains, and it exists because commercial property carries risks housing largely doesn't.

Vacancy risk cuts the other way, and it's sector-specific

Housing's tight supply shows up directly in vacancy data: SQM Research measured the national residential vacancy rate at 1.3 per cent in July 2026, essentially unchanged for months, and a vacant rental is typically readvertised and re-let within days to a couple of weeks. Commercial vacancy is a different story, and it varies enormously by sector. The Property Council of Australia's July 2026 Office Market Report put national office vacancy at 16.1 per cent, up from 15.8 per cent six months earlier, with CBD vacancy around 14.9 per cent and non-CBD space worse at roughly 18.9 per cent. Industrial space is nowhere near as exposed: JLL reported national industrial vacancy at a comparatively tight 4.8 per cent in the second quarter of 2026. Even at the tighter end, that is multiples of the residential rate, and the bigger issue for a commercial landlord is concentration: a single-tenant asset is effectively either 100 per cent let or 100 per cent vacant, and refilling a vacant warehouse, showroom or office floor commonly takes months rather than weeks, all while the mortgage keeps running.

Commercial leases shift costs, and GST, onto the tenant

A standard residential tenancy leaves the landlord carrying council rates, land tax, building insurance, most repairs and the property manager's fee, none of which can be charged back to the tenant, and residential rent itself is input-taxed, so no GST applies either way. A commercial lease usually works in reverse. Under a typical net lease, the tenant reimburses outgoings such as rates, land tax (where the lease allows it), insurance and common-area costs on top of rent, and where the landlord is registered or required to be registered for GST, that tax applies to both the rent and the recovered outgoings, a point the Queensland Small Business Commissioner's guidance (citing the ATO's GSTD 2000/10) spells out clearly. That structure makes a commercial landlord's net income far more predictable once a tenant is in place, but it also means more complex leases to draft, negotiate and administer than a standard residential tenancy agreement.

Deposits and lending terms are built differently too

Residential lenders will go to 80 per cent LVR (a 20 per cent deposit) for their sharpest rates, and considerably further than that under government deposit schemes or with lenders mortgage insurance. Commercial lending is more conservative and more varied: major banks often cap commercial LVR around 65 to 70 per cent, non-bank lenders sometimes stretch to 80 per cent for a strong owner-occupier deal, and the exact figure moves with the asset type, the loan size and the strength of the business behind it, typically leaving a buyer putting down somewhere between a quarter and a third of the purchase price. Prop Weekly has covered the mechanics of that gap, and the SMSF route into commercial property, in more detail elsewhere.

Tax settings are starting to diverge as well

The 2026-27 Federal Budget proposes limiting negative gearing on established residential investment properties from 1 July 2027, so that losses could only offset rental or property income rather than salary or other income; newly built residential properties would keep full negative gearing and the capital gains tax discount. Commercial property, along with shares and other investment assets, is explicitly carved out of the change. That is still a budget proposal rather than law, and the transitional detail differs between advisory summaries, but it is a live example of the two asset classes being treated differently by tax policy, on top of everything else that already separates them.

None of this makes one asset class objectively better than the other. Housing offers a lower but steadier return, a far deeper pool of lenders and buyers, and a vacancy you can usually fix in a fortnight. Commercial property offers a materially higher income return and leases that push running costs onto the tenant, in exchange for a bigger deposit, a tighter circle of lenders, and the chance that a single vacancy sits empty for months. Which trade-off suits an investor depends on their capital base, their appetite for active lease management and how long they can service a loan on an empty building, not on the headline yield alone.

Gross yield, the common starting point Gross rental yield = (annual gross rent ÷ purchase price) × 100. It's the figure most often quoted for both asset classes, but a commercial cap rate is typically a net figure calculated after outgoings are passed through to the tenant, so comparing it directly against a residential gross yield overstates the commercial premium unless you adjust for that difference first.
